OV/UV_TRIP config kind of return probaly off by 1000 * (set im V return in mV)

	ic_conf->cell_uv_limit =

of by a factor of 1000 (adc_gain is in µV/LSB)

ic_conf->cell_uv_limit =
    ((0x1000UL | (uv_trip << 4)) * dev_data->adc_gain / 1000.0 + dev_data->adc_offset) / 1000.0;

and
for ti manual SLUSBK2I – page 22 OV trip level is mapped to “10-XXXX-XXXX–1000”.

therefor the (1U << 13 | ov_trip << 4) should probaly be (1U << 13 | ov_trip << 4|0x8) to match the effective value

ic_conf->cell_ov_limit = 
   ((0x2008UL | (ov_trip << 4)) * dev_data->adc_gain / 1000.0 + dev_data->adc_offset) / 1000.0;
